I would say that you were at fault here.
My guess is that your primary love language is acts of service. Now, understandably, this is really something admirable, and those who have similar "attunement" to this would be better able to understand it and reciprocate it. My guess is that she wanted something from you, and that you were too focused on this that you really didn't see what she even wanted and recognized the magnitude of it. Second, it sounded like you tried to take charge in organizing the dom and from what I saw in the OP, it seemed like she didn't have much input in it. Perhaps she was uncomfortable or apprehensive. Perhaps she wanted to be able to wait until you both could have a better time.
That is where the misunderstanding ends.
But when you explicitly belittled her when she was not well, you were completely in the wrong. Love needs EMPATHY above all, and because you didn't even show sympathy, but rather said "what you feel and think is unimportant and what you think is wrong", you didn't care and were keen on showing it.
The biggest problem is that you outright refused to come to an understanding or to acknowledge her. I don't really feel sorry for you; her reaction seems reasonable.
